The CPU of a computer has a memory unit with 32-bit words. The ISA for the processor has 110 instructions. All instructions are stored in one memory word. Instructions have an op-code and two address fields: one for a memory address and one for a registered address. The chip has 8 user-addressable registers. (a) How many bits are required to specify (i) the op-code (ii) the registers (iii) memory address in the instruction? (b) What is the maximum allowable size of the memory?
